I'm not sure what the issue is, but here are some thoughts:

1) This is a known error message by Altera. They suggest using Qsys instead of SOPCBuilder: https://www.altera.com/support/support-resources/knowledge-base/solutions/fb96838.html

2) Prior to the error message you have a lot of warnings related to cpu_CRC_inst: " parameter is described in TCL description but not in HDL file". I wonder how you generated the tcl file: did you write it by hand or use SOPC builder?

I know in Qsys, you can import your HDL files and make a library block. This will generate the appropriate TCL file that can be instantiated in the Qsys system. Sometimes Qsys can make mistakes (it's pretty stupid), so you can manually edit the TCL script to fix up the mistakes.

3) Maybe this is a license issue...

I think your best bet would be to upgrade to 13.1 and use Qsys. This version seems to be pretty stable - it's what I use and I've never come across this issue.

Let me know what you think.
